(Chemical Equation Presented) Expanding rings: An intermediate organorhodium(I) species formed in the RhI-catalyzed reaction of acetylenic β-ketoesters and β-diketones with aryl boronic acids undergoes intramolecular nucleophilic addition to a ketone carbonyl group. The ensuing ring-opening reaction of the resulting cyclobutanols results in acyl 1,3-migration leading to the development of a two-carbon-atom ring-expansion reaction.
